More Information
Summary:An air-blowing tripping mechanism that is driven by gas, and includes a housing having a sealing cavity with an air-blowing channel blocked by an insulating partition plate that is blown by the gas to move, whereby the gas enters the sealing cavity, and a push rod rotationally connected to the housing. The push rod includes a rotating arm rotationally connected aside of the sealing cavity, and a reset arm. One end of the rotating arm has an operating portion opposite to an operating mechanism of a circuit breaker, and the other end of the rotating arm has an air-blowing end that extends into the sealing cavity, is located on one side of the insulating partition plate and can drive the rotating arm to rotate under the action of the gas. The reset arm is on the rotating arm and used for driving the push rod to reset.
